Webb9 sep. 2024 · Least-squares reverse time migration (LSRTM) can eliminate imaging artifacts in an iterative way based on the concept of inversion, and it can restore imaging amplitude step by step. LSRTM can provide a high-resolution migration section and can be applied to irregular and poor-quality seismic data and achieve good results. Webb13 apr. 2024 · We observe that while the Hessian is not absolutely necessary for the computation of the least squares surfaces, its availability is crucial for the computation of gradients in the outer coil optimization problem we consider in Sec. III B, when the least squares optimality condition is used as constraint within the coil optimization problem.
Webb3. Idempotency A square matrix a is called idempotent3 when a2 = a (and so ak = a for any higher power k). Again, by writing out the multiplication, H2 = H, so it’s idempotent. Idemopotency, Projection, Geometry Idempotency seems like the most obscure of these properties, but it’s actually one of the more important. y and mb are n ... WebbSum of squares and semide nite programming If a polynomial is nonnegative, can we write it in a way that its nonnegativity becomes obvious? This is the meta-question behind Hilbert’s 17th problem. As the title of this lecture suggests, one way to achieve this goal is to try to write the polynomial as a sum of squares of polynomials.

WebbAhead geological prospecting, which can estimate adverse geology ahead of the tunnel face, is necessary in the process of tunnel construction. Due to its long detection range and good recognition effect on the interface, the seismic method is widely used in tunnel ahead prospecting. However, the observation space in tunnels is quite narrow compared to …
